fix(ci): mac Nuitka 构建前清掉 steamworks/ 里的非 mac native libs (#1339)

Mac arm64 / x64 的 build-desktop nightly 因 `--include-package=steamworks`
让 Nuitka 把 repo 里 checked-in 的 Linux ELF `SteamworksPy.so` 当 package
data 一起 bundle，arch 检查 FATAL：

  FATAL: cannot use file '.../steamworks/SteamworksPy.so'
  (ELF 64-bit LSB shared object, x86-64, ...) to build arch 'arm64' result

之前的 `--include-data-files` 已按 OS gate，但管不住 `--include-package`
对包目录的自动 traverse。直接在 nuitka 之前删掉非本平台的 native libs
最简单确定。同步给 Linux/Windows 分支补上对偶清理，防止同类回归。
